T0 all whom, it may concern:

Be it known that l, FRANoIs Hoes, a cit1- Zen of the Dominion of Canada, and resident of Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Locomotive Tenders, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to improvements in locomotive tenders, and has as its object to provide a means for advancing the coal in the fuel bin of the tender so that it will be within easy reach of the fireman.

The invention consists of a structure such as is hereinafter described, and as illustrated in the accompanying drawings, in which- Fig. l is detail central vertical sectional View of the tender, the coal-advancing mechanism being shown in side elevation; and

Fig. 2 is a detail plan view thereof.

The fuel bin of the tender is of the general form in common use, having slopingside walls 10, 1.1, a rear slope sheet 12, a floor 13 the forward end of which constitutes a shoveling platform, and a coal gate 14.

The fioor 13 is apertured to receive a re volving plate 16, the size of this aperture and plate being preferably such that the lower portions of the side walls and slope sheet are necessarily cut away, as indicated by the dotted line 15 and the vertical wall 15 Rising from the plate 16 are plurality of partitions 17, of any desired height. here shown as rising the center of the plate to the level of the upper margins of the side walls 10, 11, and sl ping downwardly toward their outer ends, as indicated at 81, dividing the space above the plate into a plurality of compartments, here shown as five in number. The plate 16 rests upon a pedestal 18, carried by the framing of the tender, and is provided with a central stub shaft 19 fitting within a suitable socket bearing 20 in the pedestal.

An annular gear rack 21 is formed on or secured to the under face of the plate 16, and is engaged by a pinion 22, carried by a vertical shaft 23, journaled in a bracket 24 mounted on the framing of the tender. A motor, conventionally shown at 25, mounted on the engine frame, drives a worm 26 engaging a worm wheel 27 mounted on the shaft 23. A pull rod 28, extending through the floor 13, is provided for controlling the motor valve shown at 80.

In service the fuel bin of the tender is filled as usual, entirely submerging the plate 16 and its radial flanges. The fireman first empties the compartment of the plate 16 which is at the forward end of the fuel bin, whereupon he operates the motor to turn the plate to bring its next compartment to the shoveling position, this operation being continued until the bin is entirely empty. As the empty compartments pass under the mass of fuel above the level of the partitions 17 they are refilled by gravity.

While an operative and preferred form of construction is shown, various changes of detail, particularly as to the height, number and character of the partitions 17 and of the driving mechanism, may be made without departing from the scope of the invention.

I claim as my invention A tender for locomotives having a fuel I bin, and. a rotatable element within the bin, and having upstanding radial partitions forming an annular series of compartments.

2. A locomotive tender comprising a fuel bin adapted to be filled with coal, a slope sheet at the rear of said fuel bin, a revoluble element having a plurality of upwardly open compartments adapted to pass successively under the mass of fuel on the slope sheet.

3. In a locomotive tender, a fuel bin adapted to be filled with coal, slope sheet at the rear thereof, and a revoluble element having plurality of compartments each adapted to pass under the mass of fuel resting upon the slope sheet and to be carried to the forward end of the fuel bin, and power means for turning the ele ent.

fuel bin 4. In a locomotive tender, 2 adapted to be filled with coal and comprising a slope sheet at the rear end thereof, a revoluble floor plate, a plurality of upstanding radial partitions carried by the plate and forming compartments, and means for rotating said plate to bring each compartment successively under the mass of fuel resting upon the slope sheet and to the forward end of the bin.

5. In a fuel bin for locomotive tenders, a

rotatable floor plate, a plurality of upstanding radial partitions carried therewith, the upper edges of said partitions being inclined outwardly.

6. In a locomotive tender, in combination, a fuel bin comprising a revoluble floor plate, upstanding partitions carried therewith, a

central pivot beneath said plate, a fixed pedestal, a socket to receive said pivot, a circular rack below said floor plate, a gear mesh- 10 ing with said rack, and means for operating said gear.
